PNEUMATIC-DESPEECH-TUBE SYSTEM.

Specification of Letters Patent.

Patented March 2, 1909.

Application filed July 20, 1907. Seria1 No. 384,726.

To all whom it may concern:

Be it known that I, CHARLES F. ST01 DARD, of Boston, Dorchester, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Pneumatic Despatch -Tube Systems, of which the following is a specification.

My invention relates to new and useful improvements in the arrangement of terminals for pneumatic despatch tube apparatus and especially to such apparatus wherein large carriers are used for the transmission of mail matter, merchandise and the like.

The object of my invention is to produce an arrangement wherein the table of the receiving terminal will be connected to the transmitting machine in such a manner as to make the re-dcspatching of carriers received easier than where the two are not connected.

In the accompai'iying drawings are illustrated a construction embodying my invention.

Figure 1 is an elevation showing a receiving terminal, a transmission terminal and the connection between the table of the receiving terminal and the transmitter. Fig. 2 is an enlarged sectional view of the connection between the table of the receiving terminal and the transmitter. Figs. 3, 4 and 5 are respectively sectional views on the lines 3-3, 4 l and 55 of Fig. 2.

Like letters of reference refer to like parts throughout the several views.

The receiving terminal A shown in Fig. 1 is the same as covered by my previous patent #742,516 and its operation can be fully understood by referring to that patent. The transmitting terminal B is the same as that described in my previous patent #742,515 and the operation of same can be fully understood by referring to that patent. The upper end of the curved scoop It is connected to the table A and the lower end is connected to the upper part of the chamber 3 of the transmitter. When a carrier, after being received on the table A is to be transmitted, it is merely slid from the table A on to the curved scoop R and into the transmit ter doing away with the necessity of lifting said carrier. It often happens that the distance between the transmitter and the table of the receiver is so short that a simple curved scoop would not answer the purpose on account of the necessarily extreme sharpness of the bend in the scoop.

In Fig. 2 is shown a carrier T passing over the curved portion of the scoop It. The outline of a sin'iple bent scoop of a section like Fig. 3, is shown by broken line It.

It will be readily seen that should the curved scoop R be constructed like Fig. 3, the carrier T would rest, not on rings T but on the middle portion of its body, which in Fig. 2 is shown below the bottom line B by a simple bent scoop. In order to avoid having the carrier bear on any portion other than the rings T, the scoop has been constructed as shown in Figs. 4 and 5. In its general formation the scoop is bent or curved longitudinally and is open on its convex side. The lower portion R of the curved scoop R is depressed as shown in Fig. 4 at the curved portion so that the carrier rings T rest just upon the upper edges R" and as will be seen in Figs. 2 and 5, the middle portion of the carrier T hangs down in the depressed portion E of the curved scoop It, while said carrier is passing over the bent portion of the curved scoop R and the carrier rests at all times on its rings TT. By this construction, it is possible to get a very quick bend on the curved scoop R, at the same time avoiding the objection of having the carrier raised at any other portion than its rings T. Another construction of this curved scoop which accomplishes the same end is to entirely leave out the portion which is shown depressed in Figs. 4 and 5.

Having thus described the nature of my invention and set forth a construction embodying the same, what I claim as new and desire to secure by Letters Patent or" the United States is:

1. In pneumatic despatch tube apparatus, a receiving terminal, an inclined transmitting terminal, and a longitudinally curved connection open on its convex side located be tween said terminals, said connection having outwardly turned edges to receive the rings of the carrier and to support the latter clear of the bottom of the connection.

2. In pneumatic despatch tube apparatus, a longitudinally curved scoop open on its convex side having outwardly turned edges tWo subscribing Witnesses, this 18th day of to receive the rings of the carrier and pro- July A. D. 1907.

Vided With a depressed bottom to clear the body of the carrier during the passage of the CHARLES STODDARD' letter. Witnesses:

In testimony whereof, I have signed my 1 L. G. BARTLETT,

name to this specification in the presence of I A. L. MEssER.
